VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 286,725, dated October 16, 1883.

Application filed August 3, 1883. (No model.)

To all whom it may concern.-

Be it known that I, CHAUNOEY M. MURCH, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and use ful Improvements inVehicle-Springs, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of this invention is to increase the utilityand facilitate the construction of the peculiar form of spring seen in Letters Patent No. 226,536, granted to me April 13, 1880. In said patent the spring is shown and described as being made of acontinuous blade or strip of steel bent into the desired loop shape; but practical experience has demonstrated the fact that the spring can be more cheaply and readily censtructed of two bent blades, which blades are reversely curved where they join each other. This junction is effected with an ordinary hinge-joint, from which latter depends a link, shackle, or other connection that supports the rear of the vehicle-body, as hereinafter more fully described,

and pointed out in the claim.

In the annexed drawings, Figure '1 is a side elevation of the simple form of my improved spring. Fig. 2 is asimilarelevationof amore complex arrangement of the same. Fig. 3 is an enlarged front elevation of the hinge-connection of the two blades of the spring.

A represents a flexible blade, strip, or plate of any suitable width or thickness, the front end of said plate being provided with an eye, B, to receive a bar or rail, that supports the vehicle-body in substantially the same manner as described in the patent previously alluded to. The rear end of this plateAcurves upwardly and forwardly, as at C, and is united by a suitable joint, D, with the curved portion E of the lower plate, F. G are clips or other keepers, that securethese plates immovably to the axle H. It will be seen that the plates A andF are in contact with each other in front of the axle H, but begin to diverge or separate inthe rear of said axle, the maximum of divergence being reached at a point about vertically above the joint D. It will also be noticed that at this joint the spring is practically S-shaped, being formed of the two reversely-curved membersC E. Such beingthe case, it will be readily understood that the moment the link or other suspender J is attached to the joint D, and the vehicle-body is supported on said link, the tendency will be to pull directly down from said joint, thereby bringing into service thereverse curves 0 E, which latter mutually support each other and prevent the spring breaking, although they permit any proper vertical play of the same. In Fig. 2 the leaf F is stiffened with an extra blade, I, beneath which one or more additional blades may be applied, thus showing that the spring may be built up to any desired strength. Whichever form is adopted, it is apparent that in case either of the plates A or F should break, the joint D can be uncoupled and a new leaf substituted for the old one, there by obviating the necessity of procuring an entirely new spring, which must occasionally be done when the spring is made in accordance with the patent previously referred to. The suspension link or shackle J may be short, as in Fig. 1, or comparatively long, as in Fig. 2, according to the peculiar shape of the vehiclebody; Finally, the loop or opening betweenthe curved portions of the plates A and F may either be relatively greater or less than is shown in the drawings, as the invention is not to be limited to the exact size or shape of said loop.

I claim as an improvement on Letters Patent No. 226,536-- A pyriform or loop spring consisting of the upper plate, A, and lower plate, F, having, respectively, reverse curves 0 E at their elevated junction D, to which latter is attached the link J, that sustains the rear of the vehicle-body, while the plate A has an eye, B, to receive the support for the front of said body, as herein described.

In testimony whereof I affix my signature in presence of two witnesses.
